“…In the present CMS study, our attention is focused on pentacene which is well-known to give high-mobility field-effect transistors and has been extensively studied [18][19][20][21]. To the best of our knowledge, there are no solvents which can dissolve pentacene stably [22]. Because of this, little is known about physicochemical properties of its cation radical which plays an essential role in the conduction process.…”

Charge-modulation spectroscopy was applied to vacuum-sublimed films of pentacene in the metal-insulator-semiconductor configuration with Parylene-C or cross-linked polymer as insulator. The spectrum exhibited several peaks in the wavelength range of 300-800 nm. The signal in the visible was ascribed to the field-modulation effect of a neutral pentacene film, while the three broad peaks in the UV exhibited field and frequency dependences different from those in the visible and were ascribed to the optical absorption due to a monocation radical of pentacene. This assignment was supported by the calculation reported earlier on the basis of the time-dependent density functional theory.

“…But FF value decreased because of poor morphologies induced by NMP solvent and pentacene [22,23]. Higher performance characteristics of the device were achieved at 2.9 wt% of pentacene doping, showing that J sc = 9.20 mA/cm 2 , FF = 0.46, V oc = 0.53 V, and a PCE of 2.28%, as shown in Figs 5 and 6.…”

“…Various researchers reported on organic photovoltaic applications of pentacene as a dopant into a hole transport layer [10], an interlayer for polymer bulk-heterojunction photovoltaic cells [11], and a donor material for p-n junction photovoltaic cells [12][13][14][15][16][17] because of a high mobility, long exciton diffusion length and well suited absorption spectrum in the solar spectrum [18][19][20][21]. Moreover, it was reported that the performance of polymer schottky diode was improved by poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)-pentacenelayer [22,23].…”

The performance characteristics of organic photovoltaic cells using pentacene as a hole conducting material have been investigated. Pentacene has been extensively studied as a p-type semiconductor in organic field-effect transistors. In this study, pentacene was incorporated into PEDOT:PSS Film to improve mobility in the hole conducting layer. Organic photovoltaic cells have been fabricated with the structure of ITO/poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT:PSS)-pentacene/CuPc/CuPc:C 60 /C 60 /BCP(bathocuproine)/Al. The power conversion efficiency was strongly dependent on the doping amount of pentacene in the PEDOT:PSSpentacene films. Fabrication parameters also affected on the performance of pentacenebased photovoltaic cells.

“…as active materials in electronic devices. Several devices have been made from this polymers, such as field effect transistor (FETs) [4], [5], Schottky diodes [6]- [8], light emitting diodes (LEDs) [9], [10], photovoltaic cells [11]. Among the conducting polymers, polyaniline has received great attention due to its good thermal and environmental stability, unique properties in conducting form and its ability to tune the electronic properties by careful choice of chemical and electrochemical preparative routes.…”

In this work polyaniline was chemically synthesized. Schottky diode was fabricated based on polyaniline as p-type semiconductor, gold as Ohmic contact and aluminum as Schottky contact. Coating of metals was carried out with physically vapour deposition method and coating of polymer was done with solvent casting method. Current-voltage (I-V) characteristics of diode were measured and current transport mechanism of diode was studied. I-V characteristics showed that Schottky diode based on pure polyaniline follows the thermionic emission mechanism. The electronic parameters of Schottky diode such as ideality factor, barrier height and reverse saturation current have been determined.
